PROBLEM TO BE SOLVED: To highly accurately determine deformation amount of an injection molded product. SOLUTION: A deformation amount calculation method for the injection molded product comprises the process which divides, models a shape of the injection molded product by a plurality of elements, and calculates the temperature distribution of each divided element, the process calculating contraction characteristics of each element based on the temperature distribution, and the process which calculates the deformation amount of the shape of the injection molded product by the structural analysis reflecting the contraction characteristics of each element. The process calculating the contraction characteristics determines anisotropic contraction main shaft for each element for the anisotropic element, changes to the isotropic element for the element having no anisotropy, and models the elements by giving different contraction characteristic for each element.
